THE AMERICAN SLICING MACHINE 00., *OFCHICLGO, ILELI- Specification ofLetters Patent.

Patented July 22, 1919.

Application filed March 1, 1919. Serial No. 280,006.

To all whom it may concern:

Be it known that we, ERNEST K. Hoou, of Indianapolis, Indiana, andWALLAca B. WOLFE, of Chicago, Illinois, have invented certain new anduseful Improvements in Sharpeners for Slicing-Machine Knives, of whichthe following is a specification.

It is customaryto provide slicing machines havin rotary knives, withsharpening stones apted to be rotated by coming into contact with thebevel portion of the knife. In some machines a stone is used on thebevel side of the knife only and in other machines an additional stoneis used to turn the bur back from the concave side of the knife. Ourinvention applies to a sharpener of this latter type, and consists inthe detailed construction hereinafter described and claimed.

The figure represents a cross section of the sharpener.

The numeral 1 represents a wheel made of emery or steel which is adaptedto contact with the concave edge of a knife 2.

This wheel is carried by a shaft 3, rotatably mounted in a bearing 4,supported on a yoke 5 carried by a post 6, rigidly secured to theslicing machine. a

It will be readily seen that this construction enables the placing ofthe wheel 1 in any desired plositlon relative to the knife 2. Inpractice t is wheel is inclined slightly to the perpendicular plane ofthe knife, and also set at a slightly advanced an le with re spect tothe axis of the lmife. is causes the edge of the knife to drive thewheel, but at a slight angle across the lane of rotation of the knife,thus grin ing the edge thereof.

The wheel 1 is held in contact with the edge of knife 2, by means of aspring 7 taka inst aball bearin 8, contacting with a col ar 9 held onshe 3 by means of a pin 10.

To move wheel 1 away from the knife slicing machine adapted to advanceshaft 3. ThlS adjusting screw is The operation of the grinder is asfollows: i

It is adjusted to a knife by manipulating the bearing 3 and yoke 5,until the proper angle is obtained.

The screw 14 is then set so that it just contacts with shaft 3 and islocked in position by means of .nut 15. Then to grind the knife barrel,11 is backed off slightly by turning it thus releasing screw 14 fromshaft 3, and allowing spring 7 to hold wheel 1 against the edge of theknife. When the kni e is sharpened the barrel 11 is advanced until screw14 forces the shaft 3 forward, and wheel 1 away from the edge of theknife.

The adjustments the attaching of the ggnder to machines in a commercialway. are aware of the facts that there are several devices of thischaracter and we do not claim it broadly.

We claim:

In a slicing machine sharpener the combination of a bearing; a shaftmounted therein; a wheel carried by said shaft adapted to contact withthe edge of a knife; a spring mounted between the rear of the bearingand an anti-friction bearin carried by the shaft; and a barrel, moun onthe bearing,

and recede; unadjustsaid barrel, adapted to contact with the en of theshaft, and means for locking it into position, substantially as and forthe purpose set forth.
